I don’t know what else to call it. It was round, a 10-12ft globe, but not wholly closed. Tines ran latitudinally, while thorns at least the length of my forearm closed the gaps between them. It was a living lockup made out of giant crab legs. Only at its equator could you squeeze through, and just then only if you gingerly pressed apart the leylines of this crustacean cage. It floated with the sea, wafting.
